Don Riley was a mechanical engineer and project manager on many advanced technology projects in the 1960s, 70s and 80s. His lifetime crowning achievment was the Clinch River Breeder Reactor Project in Tennessee in the1970s.. He managed construction of a first of a kind, advanced nuclear power plant and kept it close to budget and schedule. He used a project management system he developed and applied it across a large, diverse group of companies and government agencies. When anti-nuclear behind-the-scenes forces succeeded to get President Carter to stop the project, Don Riley was removed from his management position and costs spiraled before Congress shut off funding. Don Riley is one of a group of outstanding nuclear power pioneers, very different that many nuclear power advocates of the 21st century who have far less qualifications, unrealistic ideas, and unachievable promises.
